Most people that solves corners first on big cubes just leaves two corners swapped (preferably UBR and URF), solves centers and AFTERWARDS solves corner parity. Some even waits until after edges, so that memo is as fresh as possible. But it's easy to forget them that way..
Also, remember that 2xT-perm makes a U2 on U-center, so you have to know how many T-perms you do, not only if it's odd/even.
